Specification of Letters Patent. Aplicacion ned october 22,1906. serial No. 340.093.

Patented Jan. 8, 190'7.

To au whom it may con/cern:

Beit known that I, ELMER E. LUTZHOFF, a citizen ofthe United States of America, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new land useful Improvements in Miter- BoXes, of whichthe following is a specifica- Theobject of my invention is to provide means for maintaining the saw of a miterboX in an elevated position therein and out of the way ofmoldings and other materials being placed therein to be mitered without detachingthe saw therefrom; and it consists of certain new and useful'features of construction and combinations of parts, all as hereinafter fully described, and specifically pointed out in the claims.

Referring to the accompanying drawings, which form a part of this specification, Fig- -ure 1 is a top plan view of av miter-box provided vvith my improvement. Fig. 2 is an elevation of the same. Fig. 3 is a section at the dotted line 33 in .Fig. v1 of parts there shown. Fig. 4 is a view showing'one of the saw-guide pins of the miter-boxbroken away mounted in the sockets `5/of the miter-box` at the dotted line 4 4 in Fig. 3. Fig. 5 is al detailed view of a spring detached from its'- hereinafter.

Like reference characters indicate corresponding arts throughout the several views.

1 is the ody of a miter-box provided with clamps 2 and 3 for securing therein materials to be mitered, the former being stationary and the latter movable and actuated by means of the screws 4. The body of the miter-box is equipped with sockets 5, provided with transverse detent bearin s 6, which may consist of the upper ends o said sockets or maybe inform of transverse recesses, as 7 in Fig. 3, in the inner `wall of the same. The sockets 5 are preferably formed integrally with the body 1 of the miter-box by casting them therewith. p

9 represents hollowsaw-guide pins slidably saw-guidepin and will be fully` described and having transverse o enings 10 therein for a purpose to be eXp ained hereinafter. The sockets 5 and saw-guide pins 9 have vertical registering slots 11 and 12 extending ltherethrough to admit a mitering-saw 13.k

14 is a preferably U-shaped spring, formed also' preferably of wire, included within each of the hollow saw-guide pins 9 and projecting a detent 15 through the transverse opening 10 therein into engagement with the transverse detent-bearing 6, Fig. 3, of the socket'.

16 represents vertical adjustable gages to prevent the teeth of the saw from descending low enough to come in contact with the body of the miter-box.

Whenever it is desired' to miter a piece of vthat will leave the operator free to place such material between one pair of the clamps 2 and 3 without detaching said saw from its guide-pins. After the material to be mitered has beenclamped in the desired position in the miter-box the operator will press upon the back of the saw with suflicient force to cause the detents 15 to spring inward, and thereby release the saw-guide pins 9, which with the saw 13 will then descend until the teeth of the latter rest upon the piece to be mitered.

Having fully described my invention, what I claim as new, and desire to secure by Let- 'ters Patent, is-

1. In combination, a socket provided with a transverse detent-bearing, a hollow sawguide pin slidably mounted therein, a spring included wi thin the hollow saw-guide pin and projecting a detent through the transverse opening in the saw-guide pin into engagement with the detent-bearing of the socket.

2. In combination, a socket provided with aftransverse detent-bearing, a hollow sawguide pin slidably mounted therein, ar U- shaped spring included within the hollow saw-guide pin and projecting a detent throughv the transverse opening thereininto engagement with the detent-bearing of the socket.
